DESCRIPTION OF EMBODIMENTS

Hereinafter, an embodiment of the present invention will be described using drawings. In all the drawings, similar constituent elements are denoted by similar reference signs and description thereof will be omitted.

First embodiment

FIG. 1 is a diagram showing an environment in which a position information transmission device 20 according to the present embodiment is used. The position information transmission device 20 is used together with a communication device 10, an in-zoo display device 30, a user terminal 40, and a staff member terminal 50. The in-zoo display device 30, the user terminal 40, and the staff member terminal 50 have a display (an example of a display).

The communication device 10 is attached to an animal in a facility, for example, an exhibition facility such as a zoo or an aquarium, using a band. Hereinafter, the facility will be described as a zoo.

There are a plurality of animals in the zoo, but the communication device 10 is attached to at least one of the plurality of animals, preferably all the animals in the zoo. The communication device 10 transmits at least information indicating a position of the communication device 10, i.e., a position of the animal to which the communication device 10 is attached, (hereinafter referred to as position information) and identification information of the communication device 10, i.e., identification information of the animal to which the communication device 10 is attached, (hereinafter referred to as a communication device ID) to the position information transmission device 20.

The position information transmission device 20 selects an animal whose position information is to be delivered using the position information and the identification information received from the communication device 10. The position information transmission device 20 transmits the position information of the selected animal to at least one of the in-zoo display device 30, the user terminal 40, and the staff member terminal 50.

The in-zoo display device 30 is, for example, a fixed display installed in the zoo. The user terminal 40 is a terminal that is operated by a person outside of the zoo or a terminal owned by a visitor. In the latter case, the user terminal 40 may be rented from the zoo or may be a terminal owned by the visitor. The staff member terminal 50 is a terminal viewed by the staff member of the zoo. Both the user terminal 40 and the staff member terminal 50 have a display and perform a display process using the position information transmitted from the position information transmission device 20.

FIG. 2 is a diagram showing an example of a functional configuration of the communication device 10. The communication device 10 includes a sensor group 110 and a communicator 120.

The sensor group 110 has a plurality of sensors. These sensors generate information about the animal to which the communication device 10 is attached. In the example shown in FIG. 2 , the sensor group 110 has a position sensor 112 and an altitude sensor 114. The position sensor 112 calculates the above-described position information (for example, latitude/longitude information), for example, by processing GPS information. The altitude sensor 114 calculates a height of the communication device 10, i.e., a height of the animal to which the communication device 10 is attached. The sensor group 110 outputs generated information (hereinafter referred to as sensing information) to the communicator 120 iteratively (for example, at regular time intervals).

The communicator 120 immediately wirelessly transmits the sensing information output by the sensor group 110 to the position information transmission device 20. Also, the communicator 120 stores the above-described communication device ID. When the sensing information is transmitted, the communicator 120 also transmits the communication device ID.

FIG. 3 is a diagram showing an example of a functional configuration of the position information transmission device 20. The position information transmission device 20 includes an acquirer 210, a processor 220, a transmitter 222, and various types of data storages. In the example shown in FIG. 3 , these data storages are a position storage 230, a schedule storage 240, an animal information storage 250, and a display data storage 260.

The acquirer 210 acquires data transmitted from the communication device 10. The processor 220 processes the data acquired by the acquirer 210 and updates the data storage described above as necessary. The transmitter 222 generates display data to be displayed by the in-zoo display device 30, the user terminal 40, and the staff member terminal 50 using the information stored in the above-described storage and transmits the generated display data to each of the in-zoo display device 30, the user terminal 40, and the staff member terminal 50. At this time, preferably, the transmitter 222 individually performs a display data generation process and a transmission process for each of the in-zoo display device 30, the user terminal 40, and the staff member terminal 50.

FIG. 4 is a diagram showing an example of information stored in the position storage 230. In the example shown in FIG. 4 , the position storage 230 stores the sensing information received together with the communication device ID for each communication device ID. In addition to the latest sensing information, the position storage 230 also stores previously received sensing information (history data).

The latest sensing information indicates the latest position of the animal. Also, the processor 220 processes the history data of the sensing information. For example, the processor 220 detects an abnormality in the communication device 10 using a history of positions of the animal indicated in the sensing information. For example, the processor 220 determines that the communication device 10 has been detached from the animal when a position and a height indicated in the sensing information have not changed for a certain time period (for example, 1 hour). At this time, the processor 220 may determine that the communication device 10 has been detached from the animal only when the position and the height indicated in the sensing information are in a specific region. The specific region is, for example, a region where the animal is unlikely to sleep. Also, when an output from a specific sensor has not been continuously obtained for a certain time period, the processor 220 may determine that the sensor has failed. When an abnormality occurs in the communication device 10, the processor 220 stores information indicating the abnormality (hereinafter referred to as abnormality information) in the position storage 230 in association with the communication device ID of the communication device 10. In the example shown in FIG. 4 , the position storage 230 also stores information indicating a type of abnormality (detachment, a failure, or the like).

FIG. 5 is a diagram showing an example of information stored in the schedule storage 240. In the example shown in FIG. 5 , the schedule storage 240 stores a date and time when the animal will be open to the public, i.e., a date and time when the animal will be assumed to be in the exhibition area, for each type or individual of the animal. The date and time for each type or individual of the animal is displayed on the in-zoo display device 30 and the user terminal 40 as necessary.

FIG. 6 is a diagram showing an example of information stored in the animal information storage 250. For each communication device ID, the animal information storage 250 stores a type and an individual name (or individual identification information) of an animal to which the communication device 10 indicated in the communication device ID is attached and a current position of the communication device 10.

In the example shown in FIG. 6 , the current position of the communication device 10 is a name of a facility where the communication device 10 is present. Specific examples of the facility name are, for example, an exhibition area (an area that is open to the public), a bedroom (a backyard), the inside of the zoo, a rental, and absence (a missing number), but the facility name is not limited thereto. The “exhibition area” indicates that the animal is in an area where the visitor can see the animal and the “bedroom” indicates that the animal is in an area where the visitor cannot see the animal “Inside of the zoo” indicates that the animal is at a place different from the “exhibition area” and the “bedroom” within the zoo and “rental” indicates that the animal is in another zoo. “Absence” indicates that no animal is wearing the communication device 10.

The above-described current position is generated by the processor 220 using the sensing information and the map information stored in the position storage 230. The map information used here is, for example, map information in which the above-described facility name is associated with latitude/longitude information indicating a range of the facility, and may be stored in advance in, for example, the animal information storage 250. The processor 220 determines a facility whose latitude/longitude information overlaps a position indicated in the sensing information among facilities as the current position.

FIG. 7 is a diagram showing an example of information stored in the display data storage 260. The display data storage 260 stores map data of the inside of the zoo that becomes the basis of the display data. Specifically, the display data storage 260 stores map data for displaying an overall view of the zoo and map data for displaying details of the exhibition area of the animal for each type of animal (i.e., animal identification information). Further, the display data storage 260 stores the current position of the animal (or an animal present in an area thereof) in association with the map data for each type of animal. This current position is similar to a current position stored in the animal information storage 250. Also, the display data storage 260 preferably stores the current position for each individual (for example, for each communication device ID).

FIG. 8 is a block diagram showing an example of a hardware configuration of the position information transmission device 20. The position information transmission device 20 includes a bus 1010, a processor 1020, a memory 1030, a storage device 1040, an input/output interface 1050, and a network interface 1060.

The bus 1010 is a data transmission path for the processor 1020, the memory 1030, the storage device 1040, the input/output interface 1050, and the network interface 1060 to transmit and receive data to and from each other. However, a method of connecting the processor 1020 and the like to each other is not limited to a bus connection.

The processor 1020 is a processor implemented by a central processing unit (CPU), a graphics processing unit (GPU), or the like.

The memory 1030 is a main storage device implemented by a random-access memory (RAM) or the like.

The storage device 1040 is an auxiliary storage device implemented by a hard disk drive (HDD), a solid-state drive (SSD), a memory card, a read-only memory (ROM), or the like. The storage device 1040 stores a program module that implements functions of the position information transmission device 20 (for example, the acquirer 210, the processor 220, and the transmitter 222). When the processor 1020 loads each of these program modules into the memory 1030 and executes each program module, each function corresponding to the program module is implemented. Also, the storage device 1040 also functions as various types of storages (for example, the position storage 230, the schedule storage 240, the animal information storage 250, and the display data storage 260).

The input/output interface 1050 is an interface for connecting the position information transmission device 20 and various types of input/output devices.

The network interface 1060 is an interface for connecting the position information transmission device 20 to other devices (for example, the communication device 10, the in-zoo display device 30, the user terminal 40, and the staff member terminal 50) on the network.

FIG. 9 is a flowchart showing an example of a process performed by the processor 220 of the position information transmission device 20. In the present flowchart, the communication device 10 is already attached to an animal and sensing information and a communication device ID are output to the position information transmission device 20 iteratively, for example, every minute.

When the acquirer 210 receives the sensing information and the communication device ID, the processor 220 performs a process of updating the position storage 230 using the sensing information and the communication device ID (step S10). A detailed example of step S10 will be described below.

Subsequently, in order to update the animal information storage 250, the processor 220 determines a current position of the animal corresponding to the communication device 10 using the sensing information (step S20).

Subsequently, the processor 220 causes the animal information storage 250 and the display data storage 260 to store the current position identified in step S20 in association with the communication device ID corresponding to the current position (step S30). In this way, the animal information storage 250 and the display data storage 260 store the latest position that is the latest current position of each animal.

FIG. 10 is a flowchart showing a detailed example of step S10 in FIG. 9 . First, the acquirer 210 iteratively performs the following process with respect to each of the plurality of communication devices 10.

First, the acquirer 210 requests the communication device 10 to transmit information. When there is a response from the communication device 10 (step S100: Yes) and the acquisition of the sensing information has succeeded (step S102: Yes), the acquirer 210 causes the position storage 230 to store the acquired sensing information (step S104). The processor 220 uses a history of the sensing information and currently acquired sensing information, determines that the communication device 10 has been detached from the animal when a position indicated in the sensing information has not changed for a certain time period (step S106: Yes), and causes the position storage 230 to store abnormality information indicating the detachment (step S108).

Also, when the processor 220 has not received a response from the communication device 10 in step S100 (step S100: No), the processor 220 causes the position storage 230 to store abnormality information indicating that there is no response in association with the communication device ID of the communication device 10 (step S108). Also, when the acquisition of the sensing information in step S102 has failed (step S102: No), the processor 220 causes the position storage 230 to store abnormality information indicating that the sensor has failed (step S108).

FIG. 11 is a diagram showing a first example of a process performed by the transmitter 222 of the position information transmission device 20. The process shown in FIG. 11 is performed when the user terminal 40 is allowed to display a map of the inside of the zoo using the information stored in the display data storage 260. FIGS. 12(A) and 12(B) show an example of a screen displayed on the user terminal 40.

First, the transmitter 222 reads the entire map data and transmits the read map data to the user terminal 40, so that the user terminal 40 is allowed to display the entire map of the zoo (step S210 and FIG. 12(A)). In this entire map, animal identification information of animals that are exhibited in the exhibition area is embedded for each exhibition area. As shown in FIG. 12(A), the user of the user terminal 40 selects a specific exhibition area from the entire map. The user terminal 40 transmits the animal identification information corresponding to the exhibition area to the position information transmission device 20 (step S220).

When the animal identification information is received from the user terminal 40, the transmitter 222 reads map data corresponding to the animal identification information and a current position of an animal corresponding to the animal identification information from the display data storage 260 (step S230). When the read position data satisfies a criterion, for example, when the animal is in the exhibition area (step S240: Yes), the transmitter 222 generates screen data using the read map data and the read position and transmits the screen data to the user terminal 40 (step S250).

When the screen data is received, the user terminal 40 performs a display process using the screen data (FIG. 12(B)). In this display process, the screen data includes, for example, an outline of the exhibition area selected in step S220 and the current position of the animal.

On the other hand, when the current position of the animal read in step S230 does not satisfy the criterion (step S240: No), the transmitter 222 generates a screen indicating that the current position of the animal does not satisfy the criterion (for example, a screen indicating that the animal is not exhibited) and transmits the screen to the user terminal 40 (step S260).

In addition to the process shown in FIG. 11 , the transmitter 222 transmits screen data to the in-zoo display device 30 and/or the staff member terminal 50.

For example, when the in-zoo display device 30 is installed for each exhibition area, the transmitter 222 causes the in-zoo display device 30 to constantly display a screen where the current position of the animal in the exhibition area is superimposed on the map of the exhibition area.

Also, when the abnormality information is stored in the position storage 230, after the transmitter 222 reads the communication device ID corresponding to the abnormality information from the position storage 230 and reads information of the animal corresponding to the communication device ID from the animal information storage 250, the abnormality information and the read information of the animal may be associated and displayed on the staff member terminal 50. At this time, the transmitter 222 may transmit the current position of the communication device 10 to the staff member terminal 50 so that the staff member terminal 50 is allowed to display the current position of the communication device 10.

Further, the transmitter 222 may perform the process shown in FIG. 11 with respect to the in-zoo display device 30 and the staff member terminal 50.

FIG. 13 is a diagram showing a second example of a process performed by the transmitter 222. The process shown in FIG. 13 is similar to the process shown in FIG. 11 , except that a list of animals (for example, FIG. 14 ) is transmitted instead of transmitting the entire map of the zoo (step S212). Specifically, the user of the user terminal 40 selects a desired animal from the list of animals. The user terminal 40 transmits the animal identification information of the selected animal to the position information transmission device 20. Subsequent processing is similar to the processing shown in FIG. 11 .

As described above, according to the present embodiment, the communication device 10 is attached to the animal The communication device 10 includes the position sensor 112. When the information transmitted from the position sensor 112 satisfies a criterion (for example, when the animal is within the exhibition area), the transmitter 222 of the position information transmission device 20 generates a screen showing the current position of the animal and transmits the screen to the user terminal 40. Thus, it is possible to provide appropriate information to a visitor to a zoo or a person who desires to visit the zoo.

Also, when an abnormality has occurred in the communication device 10, the transmitter 222 causes the staff member terminal 50 to perform a display process indicating the abnormality. Accordingly, a zoo staff member can easily ascertain that an abnormality has occurred in the communication device 10.

Second Embodiment

FIG. 15 is a diagram showing a functional configuration of a communication device 10 according to the present embodiment. The configuration of the communication device 10 according to the present embodiment is similar to that of the first embodiment, except that a sensor group 110 further includes a state sensor 116.

The state sensor 116 generates information (hereinafter referred to as state information) indicating a state of the animal to which the communication device 10 is attached. The state information preferably includes state information of the animal, for example, such as a heart rate, a body temperature, and a respiration rate. This state information is transmitted as a part of the sensing information to a position information transmission device 20. The position information transmission device 20 uses the state information to determine an activity state (for example, acting, sleeping, or eating) of the animal.

FIG. 16 is a diagram showing a functional configuration of the position information transmission device 20 according to the present embodiment. The position information transmission device 20 according to the present embodiment is similar to the position information transmission device 20 according to the first embodiment, except that a position storage 230 and an animal information storage 250 have different data configurations and a habit information storage 270 is further provided.

FIG. 17 is a diagram showing an example of the data configuration of the position storage 230 according to the present embodiment. The configuration of the position storage 230 in the present embodiment is similar to the configuration of the position storage 230 according to the first embodiment, except that state information is further stored for each communication device ID.

FIG. 18 is a diagram showing an example of the data configuration of the animal information storage 250 according to the present embodiment. The configuration of the animal information storage 250 in the present embodiment is similar to the configuration of the animal information storage 250 according to the first embodiment, except that an activity state is further stored for each communication device ID. The activity state indicates, for example, whether the animal is acting, sleeping, or eating, and is generated by a processor 220 of the position information transmission device 20 processing state information. The animal information storage 250 also stores statistical data of the activity state for each communication device ID.

FIG. 19 is a diagram showing an example of the data configuration of the habit information storage 270. As described above, the habit information storage 270 stores habits of the animal to which the communication device 10 is attached for each communication device ID together with a time point when the habit is likely to be performed. For example, in the example shown in FIG. 19 , the habit information storage 270 stores a time point when a certain animal has breakfast, a time point when a specific activity (for example, climbing a tree or playing in the water) is performed, and a time point of sleeping as habit information. The habit information is generated by the processor 220 processing the statistical data of the activity state.

FIG. 20 is a diagram showing an example of a process performed by the processor 220 according to the present embodiment. The process shown in FIG. 20 corresponds to the process described with reference to FIG. 9 in the first embodiment.

First, the processor 220 performs a process shown in step S10. Subsequently, the processor 220 determines a position and an activity state of the animal (step S22) and updates the storage (step S30).

FIG. 21 is a diagram showing a display example of an in-zoo display device 30 in the present embodiment. In the example shown in FIG. 21 , the in-zoo display device 30 displays the information transmitted in step S250 of FIG. 11 . Specifically, the in-zoo display device 30 displays the presence/absence (attendance) of the exhibition of a specific animal (individual), a current activity state, and habit information.

Also, the position information transmission device 20 may cause a user terminal 40 to display a screen shown in FIG. 21 . In this case, a transmitter 222 acquires animal identification information of a desired animal from the user terminal 40 and transmits habit information associated with a communication device ID corresponding to the animal identification information to the user terminal 40.

As described above, effects similar to those of the first embodiment can also be obtained in the present embodiment. Also, the communication device 10 includes the state sensor 116. The position information transmission device 20 determines the activity state of the animal using a detection result of the state sensor 116 and causes the in-zoo display device 30 and/or the user terminal 40 to display the activity state. Accordingly, a visitor to a zoo (an example of a visitor) or a person who desires to visit the zoo can easily ascertain the current activity state of the target animal. Also, as shown in FIG. 21 , the position information transmission device 20 causes the in-zoo display device 30 and the user terminal 40 to further display habit information for each animal. Accordingly, a visitor to a zoo or a person who desires to visit the zoo can easily ascertain when the target animal will be likely to be in a desired activity state.

Third Embodiment

FIG. 22 is a diagram showing an environment in which a position information transmission device 20 according to the present embodiment is used. The configuration of the position information transmission device 20 in the present embodiment is similar to the configuration of the position information transmission device 20 according to the second embodiment, except that information is further acquired from an imaging device 12 and a distance sensor 14 and the information is processed.

At least one imaging device 12 is provided for each of the plurality of exhibition areas. When a plurality of imaging devices 12 are provided in one exhibition area, these imaging devices 12 are installed at places different from each other. The imaging device 12 iteratively generates an image of the exhibition area and transmits the image to the position information transmission device 20 together with information for identifying the imaging device 12 (hereinafter referred to as an imaging device ID). Thus, the image transmitted by the imaging device 12 shows the animals in the exhibition area.

The distance sensor 14 is paired with the imaging device 12 and is provided at the same place as the imaging device 12. The distance sensor 14 measures a distance from the distance sensor 14 to the animal in the imaging area of the imaging device 12. The distance sensor 14 transmits the generated distance information to the position information transmission device 20 together with the information for identifying the distance sensor 14 (hereinafter referred to as a distance sensor ID). The distance information is used to select the imaging device 12 closest to the animal when the same animal is shown in the plurality of imaging devices 12.

FIG. 23 is a diagram showing an example of a functional configuration of the position information transmission device 20 according to the present embodiment. The configuration of the position information transmission device 20 according to the present embodiment is similar to the configuration of the position information transmission device 20 according to the second embodiment, except that an image storage 280 and a feature quantity storage 290 are provided.

FIG. 24 is a diagram showing an example of data stored in the image storage 280. In the example shown in FIG. 24 , the image storage 280 stores an imaging device ID of the imaging device 12 installed in the exhibition area of the animal and a distance sensor ID of the distance sensor 14 installed in the exhibition area according to the animal identification information. The image storage 280 further stores images generated by the imaging device 12 corresponding to the imaging device ID and distance information generated by the distance sensor 14 corresponding to the distance sensor ID. The image storage 280 also stores log data of these images and the distance information.

FIG. 25 is a diagram showing an example of data stored in the feature quantity storage 290. In the example shown in FIG. 25 , the feature quantity storage 290 stores a feature quantity of each animal used in image processing. Here, preferably, the feature quantity storage 290 stores a feature quantity for each individual animal.

FIG. 26 is a diagram showing an example of a process performed by a processor 220 according to the present embodiment. In the present embodiment, the processor 220 processes information generated by the imaging device 12 and the distance sensor 14 in addition to the process shown in the second embodiment. FIG. 26 shows an example of the present process.

First, the imaging device 12 transmits a generated image to the position information transmission device 20 together with an imaging device ID. At this time, the imaging device 12 may transmit the image to the position information transmission device 20 only when the animal is shown in the generated image. The acquirer 210 of the position information transmission device 20 acquires this information.

When an image and an imaging device ID are acquired from the acquirer 210 (step S300), the processor 220 of the position information transmission device 20 causes a currently acquired image to be stored in an area of the image storage 280 corresponding to the imaging device ID (step S302). The processor 220 determines whether or not the feature quantity stored in the feature quantity storage 290 is included in the currently acquired image (step S304). At this time, preferably, the processor 220 sets the feature quantity of the animal corresponding to the imaging device ID as a processing target. When the feature quantity is included in the image (step S304: Yes), the processor 220 instructs the distance sensor 14 corresponding to the imaging device ID to measure a distance to an animal. Subsequently, the distance sensor 14 generates distance information indicating the distance to the animal and transmits the distance information to the position information transmission device 20 (step S306).

When the plurality of imaging devices 12 have photographed the same animal (step S308: Yes), the transmitter 222 of the position information transmission device 20 selects an image to be delivered to the in-zoo display device 30 and the user terminal 40 using the distance information generated by the distance sensor 14 (step S310). For example, the transmitter 222 selects an image generated by the imaging device 12 corresponding to the distance sensor 14 showing a value with the smallest distance information as the image to be delivered. The transmitter 222 delivers the selected image to the in-zoo display device 30 and the user terminal 40 (step S312).

Also, when only one imaging device 12 has photographed the animal (step S308: No), the transmitter 222 delivers the image generated by the imaging device 12 to the in-zoo display device 30 and the user terminal 40 (step S312). At this time, the transmitter 222 may deliver the image only to the user terminal 40 that has registered that the image related to the animal is desired to be delivered.

Also, the processor 220 may generate state information by processing the image generated by the imaging device 12. In this case, a sensor group 110 of the communication device 10 may not have the state sensor 116.

As described above, effects similar to those of the second embodiment can also be obtained in the present embodiment. Also, when the animal is shown in the image generated by the imaging device 12, the position information transmission device 20 delivers the image to the in-zoo display device 30 and the user terminal 40. Accordingly, it is possible to provide appropriate information to a visitor to a zoo or a person who desires to visit the zoo.
